I would assume local as well. I have had to use broadcast relays, thankfully not in this case.
Been restarted several times.
No, doesn't have an interface on that network. That network is still reachable, but that doesn't matter either. Since it was auto-added, not manually added via an IP address, there is no mechanism to remove it short of wiping it clean and starting over.
I have forced the old network to be unreachable, for what it's worth, and the above still applies.
